Accel 17 Click Board™

Product Code: MIKROE-4855

How Does The Accel 17 Click Board™ Work? The Accel 17 Click Board™ as its foundation uses the MXC62320MP, a complete dual-axis acceleration measurement system fabricated on a monolithic CMOS process from MEMSIC. The MXC62320MP operation is based on heat transfer by natural convection and operates like other accelerometers, except it is a gas in the MEMSIC sensor. It can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity), with full-scale acceleration measurements, a range of ±2g. It also comes with embedded Power Up/Down and self-test function, resolution better than 1mg, and >50.000g shock survival rating. In addition to all these features, it also has excellent temperature stability and low power consumption/low active current. This accelerometer can enter a Power-Down mode writing a command [xxxxxxx1] into the accelerometer's internal register, while a Wake-Up operation is performed when a command of [xxxxxxx0] is written into the same register.

Note that the MXC62320MP needs about 75ms (typical) for Power-Up time. The Accel 17 Click Board™ communicates with MCU using a standard I2C 2-Wire interface that supports 400kHz Fast Mode operation. Since the sensor for operation requires a 3.3V logic voltage level only, this Click board™ also features the PCA9306 voltage-level translator from Texas Instruments. The I2C interface bus lines are routed to the dual bidirectional voltage-level translator, allowing this Click board™ to work with both 3.3V and 5V MCUs properly. TheAccel 17 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VIO SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development.
